React Bootstrap全新,我一直在尝试为组件添加一些自定义样式。
我可以通过使用chrome检查器找到类名来从Nav中删除边界半径,但我还没有能够为我的NavItems添加悬停效果。
这是我的组件。
<Navbar inverse collapseOnSelect className="nav-bar">
<Navbar.Header>
<Navbar.Brand>
<a href="#">efrt</a>
</Navbar.Brand>
<Navbar.Toggle />
</Navbar.Header>
<Navbar.Collapse>
<Nav>
<NavItem eventKey={1} href="#">Features</NavItem>
<NavItem eventKey={2} href="#">Who we Are</NavItem>
</Nav>
<Navbar.Form pullRight>
<UniversalButton style="primary" name='Login' />
</Navbar.Form>
<Nav pullRight>
<NavDropdown eventKey={3} title="Signup" id="basic-nav-dropdown">
<MenuItem eventKey={3.3}>Member</MenuItem>
<MenuItem divider />
<MenuItem eventKey={3.3}>Coach</MenuItem>
</NavDropdown>
</Nav>
</Navbar.Collapse>
</Navbar>
从Chrome检查器复制,我得到以下内容作为我想要进行更改的类/元素
.navbar-inverse .navbar-nav>li>a {
color: #9d9d9d;
}
当我尝试以下时,没有任何反应。我尝试添加自定义类名也没有效果。
.navbar-inverse.navbar-nav>li>a:hover {
background: grey;
}
任何帮助表示感谢:)!
答案 0 :(得分:3)
.navbar-inverse
.navbar-nav
之后您遗漏了一个空格,因为.navbar-inverse .navbar-nav > li > a:hover {
background-color: gray;
}
是孩子:
const { Navbar, Nav, NavItem, NavDropdown, MenuItem } = ReactBootstrap;
class App extends React.Component {
render() {
return (
<div>
<Navbar inverse collapseOnSelect className="nav-bar">
<Navbar.Header>
<Navbar.Brand>
<a href="#">efrt</a>
</Navbar.Brand>
<Navbar.Toggle />
</Navbar.Header>
<Navbar.Collapse>
<Nav>
<NavItem eventKey={1} href="#">
Features
</NavItem>
<NavItem eventKey={2} href="#">
Who we Are
</NavItem>
</Nav>
<Navbar.Form pullRight />
<Nav pullRight>
<NavDropdown eventKey={3} title="Signup" id="basic-nav-dropdown">
<MenuItem eventKey={3.3}>Member</MenuItem>
<MenuItem divider />
<MenuItem eventKey={3.3}>Coach</MenuItem>
</NavDropdown>
</Nav>
</Navbar.Collapse>
</Navbar>
</div>
);
}
}
ReactDOM.render(<App />, document.getElementById("root"));
运行示例:

<style>
.navbar-inverse .navbar-nav>li>a:hover {

}
</style>
<div id="root"></div>
while True:
start = input("Enter Roll or Quit? ")
